10.6.6 = Vine System Server more stable?

I don’t know what it is, but since I’ve upgraded to Mac OS 10.6.6, my Vine system server (3.1.2 beta) seems to be a lot more stable. It used to crash/restart every day or so, forcing me to reconnect, but now I can’t even remember the last time that happened (and I’m not that old :).

Moreover, I used to have a problem getting my SHIFT key status to transmit, but that also seems more stable now.

Anyone else notice that? Did 10.6.6 fix some networking bug or something?
